Display- / set value
Description
Flow fixed temperature
Setting value
Flow
fixed
temperature
to
be
maintained
constantly during the set heating time. For the
operating mode feed flow fixed..
Room influence
Setting value
Factor for the influence of the room temperature.
This value is adjustable between 0 and 10. The
higher the value selected, the more influence a
difference in the actual room temperature will have
on the calculation of the flow fixed temperature.
Correction
Setting value
This value is adjustable between - 5 and + 5. This
value multiplied by 2 (fixed value) gives the
influence on the flow fixed temperature. Only
possible in Heating time mode, Continuous
heating and continuous lowering.
Kneeling influence
Setting value
Factor for the influence of the lowering
temperature. This value is adjustable between 0
and 10. The higher the value selected, the more
influence the room temperature will have on the
calculation of the flow fixed temperature.
End run
Setting value
Limit value for the outside temperature. If the
outside temperature drops below this value, the
pump will run constantly in order to stop the
system from freezing up. (Setting range from - 10
to + 10)
Day
middle
switching
temperature
Setting value
The day middle switching temperature already
mentioned works as an average value generator.
This means that from when it is first switched on,
an internal average temperature generator of the
external temperature starts up. This runs
continuously in the background. Should the
daytime average target temperature that you have
set be exceeded, this is an indication for the
control system that it should be changed to the
automatic summer mode. Here all heating circuits
are deactivated and so no heat demand can be
made. This means that the higher the value set for
the day middle switching temperature, the later the
change-over to summer mode will then be.
Temp. Increase
Setting value
Required temperature setting. Increase required
due to reduced efficiency. You can enter an
amount to be added to the target temperature of
the storage tank circuit here
Outside temp. increase
Setting value
Activation of outside temperature sensor.
Balancing outside sensor
Setting value
Setting balancing for the outside sensor.
Hot water tank priority
Setting value
Activation Hot water tank priority
Kneeling barrier
Setting value
Activation Kneeling barrier
Flow max. temperature
Setting value
Maximum Flow temperature (however this value
can be exceeded by 5 °C for the purpose of
regulation
Root point temperature
Setting value
Setting the Root point temperature.
